JOINT AND CONNECTION FOR CROSSED OR ABUTTING PARTS.

Specification of Letters Patent.

Patented Jan. 16, 1912.

Application led April 8, 1909. Serial N0. 488,262. y

To' all whom. it may concern Beit known that I, HEINRICH W'EiGANp, a citizen of the German Empire, and resident of 4 Bismarckstrasse, Hattingen-Ruhr, Germany, have invented certain new and useful Improvements in Joints and Connections for Crossed or Abutting Parts, of

which the following is a' specification.

This invention relates to the joining together of parts crossing or abutting against each other, without rivets, tenons, bosses or the like, and substantially consists in making one of the part-s penetrate or traverse the other, and upsetting 'or melting down the edge of the former in a cavity in the latter.

In the accompanying drawings: Figure .lv is a perspective view of my im rove'd joint. showing it applied to a pair o intersecting U-beams; Fig. 2 a sectional side view of a modification; Fig. 3 an end view of Fig. 2; Fig. 4 a cross section of a further modification; Fig. 5 a longitudinal section of Fig. 4; Fig. (l a ground plan thereof; Fig. 7 a front view of a further modification; Fig. 8 a side view thereof; Fig. 9 a plan of afurther mmlification: Fig. 10 a cross section thereof; Fig. 11 a plan of a further modification; Fig. 12 a cross section thereof; Fig. 13 a plan of a further modification; Fig. 11 a cross section thereof; Fig. 15 a longitudinal section of a further modification; Fig. 16 a cross section thereof; Fig. 17 a. ground plan of a further modification; Fig. 18 a side view thereof: Fig. 19 u perspective view of a further modification; Fig. 20 a rear view of :i still further modification, and Fig. 21 a side view thereof.

vReferring in the tirst place to Fig. 1, the channel-iron 1 has in its web two slots which also extend a short distance into its flanges and enable the flanges of the bar 2 to engage the bar 1. The flanges of the bar 2 are fiattened or upset to form beads 3, which make a. perfectly .secure connection between the two bars.

In Figs. 2 and 3 the strip or pl'ate 4 has hemispherical. hollow protubera-nces 5 with longitudinal slots of such Width that the flat bars G fit exactly thereinto and of such length that the parts 6 abut against the fiat undersurface of the part 4. Those portions of the parts G which protrude into the cavitier` of the protuberances 5 are upset to form heads or heads 3. which lock the parts together. For this method of 'connection it is essential that the width of the part 6 e.\

ceeds the length of the slots. l

If' a plurality of bars have to be fixed across a transverse bar, the latter is prefer ably made of U-seetion, or the like, so that the separate proturbanees 5 may be dispensed with. In Figs. 4, 5 and 6 the transverse bars 6 are partly sunk into slots in t-he bar 7, the connection being made by upsetting the edges of the bars in the channel of the bar 7. The originally-considerable strengt-h of the channel bars, due to their shape, is further increased by the upsetting 'or beadin at the edges.

Figs. 7 and 8 i lustrate the connection of two bars oblique to each other. A strut 11 abuts against one side of a plate 9, which has a channel 12 in which part of he edge of bar 11 is upset to form a bead 3. Plate 9 is then placed with its opposite side against a bar 8, and the semi-cylindrical. hollow protuberance 10 of the said plate is penetrated by the bar 8. The connection between the bar8 and the plate 9 is made by upsetting the edge of the bar 8, to 'form a bead 3 within the cavity of the protuberance.

F 9 and l() show a transverse bar 80, with two vertical bars 110 abutting against it to form a cross, all the bars being in the same plane. The plate 90 at the junction of the bars is fastened to the har 8O by beads 3 formed at.- 13, 13 in an annular cavity of the plate, traversed by the bar 80. The other two bars 110 are similarly Jfastened by means of heads 3 made at 14.- and 15.

In Figs. 11 and 12 the two rods 16 and 17 cross each other with a small space bet-Ween them and are joined together by means of a plate 9, to which the rear bar is locked by means of heads formed in cavities 13, the front bar being locked to the plate by means of beads formed in oppositely directed cavities 14 and 15. The plate 9 in this ease serves solely for holding the two bars together, Without having a supportingfunction as in Figs. 9 and 10.

Figs. 13 and 14 illustrate the connection of an ornamental head 18 to the end of a bar. The head 18 has a socket 19 which embraces the end of the bar 20, and the edges of which are upset to engage a transverse cavity 21 in the bar. v

-In Figs. 15 and 16 the bars 22 and 23' are channeled and abut against each other at a.

right angle. An angle-piece 24 placed in the channel, at the joint has transverse grooves 25,and 26 at the ends of which the edges ofthe bars 22 and 23 are upset, so-that they engage the said grooves and lock 'the bars to the angle-piece. The fastening 'is 'totally invisible from outside.

Figs. 17 and 18 represent a boot-scraper.

spacing of lScrapers 27; The ends of these Scrapers are projected through th'ese'bulges and are then upset. Intermediate the end bars 28, Scrapers 27 are supported upon a flanged channel bar 30 which is slitted in alinement with Scrapers 27, so that the lower sides of the Scrapers may be projected into the conc'vity of the bar and may then be upset. J

vIn Fig. 19, the pintle of a door hinge'has a squared.endpiece Bl provided with a series of cavities or grooves 32 into which project l formed which mechanically locks the parts ltogether. vMoreover, the sharp protruding edges are freely exposed to the llame, so

a corresponding series ot fianges or Ibeads formed on a hollow post 3 which incloses said end-piece.

The ornamental head-plate 34 shown iri Figs. 2O and 21 has a kind of pocket 35 for adjacent parts.

the flange 36 of the bar 37, the plate being slot-ted so that the flange can traverse the pocket and be beaten flat against the back of the plate. cured to the bar, and can not be rotated.

In some cases the small dimensions of the parts to be joined together, or the shape of the article to be produced, forexample a grating or boot-scraper, may render it difficult or inconvenient to support the parts in a -manner which will allow of upsetting the edges as described, and for manufacturing on a large scale it may also be desirable to have a more rapid method of enlarging the edges. ln such cases it is often convenient to melt down the protrudin edge in the cavity, to'fornx a kind of hea the melting being preferably effected by the means commonly used for the urpose of auto enous soldering, such as a game-arc or oxy ydroand vbin-ds gagementof the slotted part with the other The plate is thus firmly sey gen bilrner, so that in addition to forming the head ,-some metal runs into the slot to ether the parts. Even as regards the soldering vor welding scribed is of advantage to the appearance and' security of the 'oint. A certain pre-' liminary connection 1s afforded by the enpart. Of the metal available-for welding, part rims into the joint, and part is burned. In the case of two tlat surfaces which merely abut one upon the other, themelting process rounds ofi'l the edges, and thus` not only red uces the area of contact but. reduces an unsightly 'joint. On the other4 and, if one of the parts has penetrated the other, and/ is freely protruding into a cavity of the latavaila-ble for welding purposes, the joint is lled'wit-h metal, and 1 n addition -a head is that the protruding metal is quickly melted, without, risk ot melting and damaging the A connection of the class described, compr`sing. a first hollowed member havinlg a transverse' slot that opens into the ho ow of said member at the aiiial center thereof.

and a second member rigidly enga ing with its longitudinal edge the outer si e of the first member and projecting with said edge in part t-hrou h the slot into the hollow of said. finst'mem er, said projecting part 'being upset (vithin' said hollow, to form a clenched connection between the members.
